For your consideration, here is the Black History 40 Documentary Collection 3 DVD Set, Semi-Sealed, from Mill Creek Entertainment, 2007, run time: 14 hours, 48 minute, made in China.  The DVDs are in nice shape.  The case is sealed at the top, but I could slip out the DVDs, for inspection and photos.  The case has a little wear on it.  It will be mailed in a box for protection.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (469.767m-.11dx15)
